Slow upload and download

I changed to viasat for faster speed and have not had the promised speed while working. Work requires I use duo mobile VPN. What can be done to improve my upload and download speeds?

Hi @denised22470,

I just ran a test from your modem and at the moment I’m seeing good speeds (considering that you are on a plan that offers download speeds of up to 30 Mbps).

Unfortunately, the VPN experience is not great over geostationary satellite, so your speeds will be slower when using a VPN.

However, so that we can better understand the difference in speeds, could you please run some tests and share screenshots of the results with us?

Here are some instructions to run this speed diagnosis: How to run a speed test from my modem?



This is with the VPN
If your service cannot support the requirements I will have to cancel.

Hi @denised22470 ,

Unfortunately due to the structure of geostationary satellite internet, VPNs tend to not work very well. However, here are a few things you can try to see if the situation improves:

There are some options you can try at first to see if the speeds improve:

  1. Choose a server closer to your physical location: The distance between your location and the VPN server can affect your connection speed.
  2. Select a server with a lower user load: VPN servers can become crowded, especially popular ones. If a server has a high number of users connected to it, it may impact your connection speed.
  3. Use a wired connection: it can provide a more stable connection.

Please let us know if there’s any difference when following these tips.


I have a hard line connection.
I do not have the option to choose what server the VPN connects to.
I am sure I am not the only customer that is required to use a VPN to work from home. What is the solution?

Hi @denised22470 ,

The geostationary satellite has compatibility issues with VPN (see VPN over Satellite - Project Faster for a description) mainly because the VPN causes our embedded TCP optimization to get bypassed. We are working with VPN vendors to improve things but have no good progress to report yet.

We apologize for the situation.
